The object of my invention is to make the loom more simple inconstruction and more certain in its operation, and, to provide afilling stop motion active between the filling supply andthe pickmeasuring mechanism.

The novel features of the invention are fully disclosed in the followingspecification and accompanying drawings, and are further pointed out inthe claims. 4

Referring to the drawings Fig. 1 is a view in elevation at one side ofthe loom but showing only portions of the loom;

Fig. 2 is a section on the line 2-2, Fig. 1;

Fig. 3 is a detail of the means for disengaging the filling from thepulling-off finger.

In the drawings the ordinary parts of the loom shown are the lay A,breast beam B, framing C, and end of crank shaft D.'

Upon the end of shaft D is a sprocket wheel, 1, and upon a stud, 2, inupper end of frame, G, is a sprocket wheel, 3. Carried and operated bythese sprockets is a chain, 4,

provided with special links, 5 and 6.

Links 5 and 6 have wings 7 and 8. Link 6 has a bridge, 9, secured towings 8, and fast in the center of said bridge 9 is a pin, 10, on whichis secured a roller, 11.

Adjustably bolted to framing C is a filling guide, 13, provided withholes, 14, 15.

Mounted on the lay A is an air-discharging nozzle 32 retained thereon bya clip 33, this nozzle being such as is usually employed in looms ofthis type for blowing the filling through the shed.

The filling 40, carried on cone, 41, supported by bracket, 42, securedon framing C, passes up through hole, 43, in end of beam B, throughholes 14 and 15 in filling guide 13 and through air nozzle 32.

As the sprocket chain moves, roller 11 engages filling thread and drawsoff a desired length; determined by the distance between. guide 13 andsprocket wheel 3.

As link 5 beginsto bend, in conformation 45 to sprocket 3, loop 12 ismoved outwards, dot- 1927. Serial at. 205,506.

ted lines Fig. 1, pushing filling of thread ofi roller 11 thus forming aloose loop at filling to be blown within the warp-sheds.

Having described my invention, what I claim as new and desire to secureby Letters Patent is- 1. In a loom having a source of filling supply andmeans to insert lengths of filling in the shed, the combination with asprocket chain, of upper and lower sprocket wheels over which it passes,means on the sprocket chain to engage said filling thread between thefilling-inserting means and the source of supply and draw off a lengthof filling thread, and means on the chain and rendered operative as thechain passes over the upper sprocket wheel to disengage said fillingthread from the pulling-off means.

2. In a loom having a source of filling supply and means for insertingfilling in the shed, the combination with a lay, of a crank shaft foroperating the latter, a sprocket chain actuated by the crank shaft,upper and lower sprocket wheels over which the sprocket chain passes,means on the sprocket chain to engage the filling thread between thesource of suplply and filling-inserting means and thereby c raw oif alength of filling thread from the source of supply, and means on thesprocket chain and rendered operative as the chain passes over one ofthe sprocket wheels to disengage the filling thread from the pulling-offmeans.

3. In a loom having a source of filling sup ply and means for insertingthe filling in the shed, the combination with a lay, of a crank shaft bywhich the lay is operated, a sprocket wheel on said crank shaft, asprocket chain passing over said sprocket wheel and provided with links,and another sprocket wheel over which said chain passes, a finger onsaid chain adapted to engage the filling thread and draw off a lengththereof from the source of supply, and means rigid with one of the linksto disengage the filling thread from the finger as the link passes overone of the sprocket Wheels.

4. In a loom having a source of supply and means to insert filling inthe shed, the 5 combination with a lay, of a sprocket chain havinglinks, means on the sprocket chain to engage said filling thread betweenthe filling inserting means and the source of supply and throw off alength of filling thread, and means rigid with one of the links andactuated by the movement of the chain passing over the sprocket wheel todisengage the filling from said finger.
